To earn back points on your Unit 2 Test (if you earned less than 34.5 out of 46):
1. Complete test corrections for Part I (Multiple Choice) on a separate sheet to the best of your ability. Test corrections should include the correct answer and where your misunderstanding happened and why the correct answer makes sense.
2. Email Ms. Rapoport (rrapoport@latinpcs.org) with the problem numbers in Part 2 and Part 3 for which you lost half or more of the points. For example, if the question was worth 5 points and you earned 2 points, you lost 3 points which is more than half. I will email you back with specific problems to work on.
All of this can be done when you get back from break, but I wanted to give you this information in case you wanted to work on it during break.

  2. If you think that we did not need to know all corresponding sides and corresponding angles are congruent, which combinations of sides and angles are enough to prove that two triangles are congruent? Experiment with as many combinations as you can think of (3 sides, 3 angles, 2 sides & 1 angle, etc.)
